The web server logic implements the HTTP protocol, manages web resources, and provides web server administrative capabilities. The web server logic shares responsibilities for managing TCP connections with the operating system. The underlying operating system manages the hardware details of the underlying computer system and provides TCP/IP network support, filesystems to hold web resources, and process management to control current computing activities.
Web servers are available in many forms:
· You can install and run general-purpose software web servers on standard computer systems.
· If you don't want the hassle of installing software, you can purchase a web server appliance, in which the software comes preinstalled and preconfigured on a computer, often in a snazzy-looking chassis.
· Given the miracles of microprocessors, some companies even offer embedded web servers implemented in a small number of computer chips, making them perfect administration consoles for consumer devices.
